This element writes tags into metadata (EXIF, IPTC and XMP) chunks, and
writes the chunks into image files (JPEG, PNG). Tags the are received as
GST_EVENT_TAG event or set by the application using <a
href="/usr/share/gtk-doc/html/gstreamer-0.10/GstTagSetter.html"
><span class="type">GstTagSetter</span></a> interface.

<p>
If this element receives a GST_TAG_EXIF, GST_TAG_IPTC or GST_TAG_XMP which
are whole chunk metadata tags, then this whole chunk will be modified by
individual tags received and written to the file. Otherwise, a new chunk
will be created from the scratch and then modified in same way.
